'Let Us' in the Bible

And the servants of the king of Syria said to him, Their gods are gods of the hills. On account of this they were stronger than we were. But let us fight against them in the plain, and surely we shall be stronger than they.

And his servants said to him, Behold now, we have heard that the kings of the house of Israel are merciful kings. Please let us put sackcloth on our loins and ropes on our heads, and go out to the king of Israel. Perhaps he will save your life.
